The QA and Validation Stack: Catch Issues Early

QA is often rushed, but small checks save huge rework. This tool stack focuses on quick validations that prevent publish time surprises.

Step 1: Validate files and formats

Use a format inspector to ensure inputs match their extensions. Confirm transparency when required and review metadata for privacy.

Try the Image Format Inspector

Try the Transparency Checker

Try the EXIF Viewer

Step 2: Validate links and pages

Check Markdown links for obvious errors and run quick status checks for critical URLs. If you are shipping a sitemap or robots rules, validate them too.

Try the Markdown Link Checker

Try the HTTP Status Checker

Step 3: Compare versions

When editing copy or subtitles, diff tools help you confirm what changed. This is especially valuable for legal and compliance updates.

Try the Text Diff Viewer

Try the SRT Time Shifter

Step 4: Naming and organization

Batch file renaming keeps assets consistent and predictable. Standardize naming before uploading to your CMS or DAM.
